* OCTTOHEX * * Return an octal value as hex. * * Excel Function: * OCT2HEX(x[,places]) * * @access public * @category Engineering Functions *

Parameters

string $x The octal number you want to convert. Number may not contain: * more than 10 octal characters (30 bits). The most significant * bit of number is the sign bit. The remaining 29 bits are * magnitude bits. Negative numbers are represented using * two's-complement notation. * If number is negative, OCT2HEX ignores places and returns a * 10-character hexadecimal number. * If number is not a valid octal number, OCT2HEX returns the * #NUM! error value. * If OCT2HEX requires more than places characters, it returns * the #NUM! error value. * @param integer $places The number of characters to use. If places is omitted, OCT2HEX * uses the minimum number of characters necessary. Places is useful * for padding the return value with leading 0s (zeros). * If places is not an integer, it is truncated. * If places is nonnumeric, OCT2HEX returns the #VALUE! error value. * If places is negative, OCT2HEX returns the #NUM! error value. * @return string
